ln the drawings, wherein is illustrated a preferred embodiment of my invention, 'the `numeral 1 designates, as a whole, a wheel, comprising a huh 2, from which radiate spokes 3, which in turn are suitably secured with a winden felly 4.

The numeral 5 designati-.s a permanent rim. which disposed upon the periphery of the :telly 4, as clearly illustrated in Fig. 2. This permanent riln has one edge thereof bent lo forni an annular portion l'. which is curved in cross-section as shown. The oppositie edge of the rim 5 is bent inwardly to forni an annulaisection 7, which engages one side ofy the telly 4 and is secured thereto by screws 8, or any suitable means. An annular section 9 iis-disposed upon the opposite side of the telly 4 and is connected with the permanent yrim .as shown at 10. The

The annular section 9 is secured upon the telly 4, by means of screws 11, or the like. The felly 4 1s provided at `spacedintervals with a plurality of e permanent rim `5 extends across each'y of the recesses or pocketsl 12, and 1s providedwith an L-shaped- Aslotf 13, having coml Patented Nov. 1, 1910.

munication 'with the pocket 12. IThe annular section is also provided with an open# ing 14 which merges into the slot 13,"andl communicates with the. pocket 12.

A demountable rim ,15 is provided to co, operate with the members above described, and the same has its-edges bent, as shown at 16, to receive and hold a portion of a pneumatic tirev 17. This demountable rim. is: `connected with thetire 17, and removably mountedl upon the permanent rim. I The clemountab e rim 15, 'has xedly 'secured thereto, a plurality of spaced inwardly er` tending locking lugs. 18, correspondin in number to the slots 13. Each 'of the loc ring lugs 18 is under-cut along its ends and one' side, as shown at 19, to fit within the L- shaped slot 13, as ,clearly illustrated in Fig. 5. Keys 20 are fixedly mounted at spaced intervals upon a removable ring 2l, which has its outer edge curved, as shown at This ring is arranged `upon the annular portion 7, and cooperates With the bent portion 6 of the permanent rim, to hold the rim 15 `upon said permanent rim. Each of the keys 20, is U-shaped in cross-section and adapted for insertion through one of the openings 14 to occupy a 'position- Within the pocket 12, to'

confine the lug 18 Within the slot13, so that .said lug engages the Wall 23 of the slot 13.

When this lug is thus confined Within the slot 13, the rim 15 cannot be removed from the permanent rim 5. The removable ring 21 is provided With a plurality of openings 24, to receive therethrough bolts 25, having their inner ends screw threaded, as shown at 26. There is a corresponding number of bolts 25 and keys 2 0, and each of the bolts'.y is Iarranged Within onev of'these keys, as clearly illustrated'in Fig. 2. The annular section :9 is provided with a plurality oflugs 27, one of' which is disposed Within each of the pockets l2. This lug is ixedly secured upon .the annular section 9 by any suitable means. Each of the lugs 27 is provided with a screvv the position shown in Fig. The ring 21 bolts 25.

' what I c aim as new and desire to secure by vto be taken as a preferred example of the threaded opening 28, to receive the screw threaded end oi" the bolt 25. The lug 27 is further provided with a frusto-conical openingr 29, which leads into the screw threaded opening 28, for the purpose. of directing the I bolt 25 into said screw threaded opening.` I

In the use of my device, the permanent i rim 5 is first secured to the felly 4, as above described, and the annular sections 7 and 9 are also connected with said felly by means of the screw, or the like. The demountable rim 15 is secured upon the tire 17, in the usual manner, and said demountable rim is then slipped uponI the permanent rim 5. The rim 15 is then given a partial rotation, whereby each of the locking lugs 19, will assume the position wit-hin the slot 13, as

clearly illustrated in F ig. 5. The ring' 2l is then positioned upon the annular section G,

whereby one of the keys 2O will be inserted within the pocket l2, to retain the lug in is removably held in place, by means of the It is thus seen that the tire 17 is permanently held upon the wheel 1, and may be easily removed, for the purpose of I wish itunderstood that the form of my invention herewlth shown and descrlbed, is

same, and that certain changes in the shape, size, and arrangement of parts, may be rei sorted to without departing from the spirit of my invention, or the scope of the subjoined claims.

Havin thus fully described my invention Letters Patent, is

1'. The combination with the felly of a wheel, of a rim permanently secured upon said felly and provided with an edge curved in cross-section, said felly being provided with a plurality of pockets, Said rim being provided with a corresponding number of slots having communication with said pockets, a demountable rim provided with edges curved in cross-section to hold a tire, said demountable rim being adapted to be removably arranged, upon said first named rim, a pluralityr of lugs connected with said demountable rnn for insertion within said slots, each' of said lugs having portions thereof underfcut to lock with the walls of the slot, a ring to be detachably connected with said felly, and a plurality of keys rigidly mounted upon said ring for insertion within said pocket, to confine said lugs within one end of said slots.

2. The combination with the felly of a wheel, of a rim permanently upon the same, and provided with a plurality of approximate l' L-shaped slots. sa'id fe ly being provided with a corresponding number of pockets in registration with said slots, a demountable rim for arrangement upon said firstnamed rim and to hold a tire, said demountable rim being provided with a plurality of lugs having their ends and Sides under-cut, a rin, r to be removably arranged upon said felly, apluralitv of keys rigidly mounted upon said ring, a lurality of bolts to hold said ringr upon said) felly, and a plurality of fixed lugs provided with screw threaded openings to coperate with said bolts.

In testimonv whereof I affix my signature in presence of two witnesses.
